Title: Improvements in or relating to methods and apparatus for bending metal to loop formation
IPC: B21D51/54
Filed: 1942-01-29
Abstract: 568,124. Making hinges and ammunition-feed links. NOVOBAX, Ltd., and OYSTON, W. R. Jan. 29, 1942, No. 1251. [Classes 83 (ii) and 83 (iv)] Angular bending; dies and formers.-A closed circular loop, for ammunition - feed links L, Fig. 3, of a Browning machine gun or for the eye of a hinge &c., is made by wrapping a substantially flat metal strip around a mandrel having an oval or other non-circular cross-section and then rotating the mandrel within the loop while this is held, preferably resiliently, in a die having the required circular cavity. In making an ammunitionfeed link, a stamped blank B, Fig. 1, is fed to the side of jaws 41, 42, Fig. 4, by mechanism operated by a rod 54 carried by a cam-actuated slide 27, which advances towards the jaws with its mandrels 28, 34, 35, Fig. 11. During this movement the mandrel 28 is advanced axially over the blank B by a weighted lever 30 and fixed cam 33, and the jaws 41, 42 are released from the action of cams 76 and levers 61 and closed by springs 43. The mandrel 28 in its lateral advance presses the middle of the blank against a spring-pressed holding-pin 55 and between the spring-closed jaws 41, so that it is wrapped around the mandrel 28 as shown in Fig. 5. A cam-operated slide 56, Fig. 11, then advances with its spring-pressed finger 57 and camplates 36, the finger engaging and pressing the blank ends E to complete the loop 20 and the cam-plates 36 advancing the mandrels 34, 35 axially over these ends. Continued advance of the slide 27 forces the loop 20 into the lower gap 46 of the spring-pressed jaws 41, 42 and causes the jaws 51, 52 to begin to wrap the ends E around the' mandrels 34, 35, Fig. 7. The loops 21, 22 are completed by the advance of jaws 51, 52 by means of cams 60, levers 61, springs 75, levers 94 and pins 95, and then of jaws 50, 53 by a further advance of the levers 61 acting through spring bolts 93, the levers 94 remaining stationary while the springs 75 are compressed. The mandrel 28 is then turned on its axis by a wheel 71, Figs. 10, 11, chain 70, lever 73 and cam 74, and returned by a spring 72. The mandrels are then withdrawn, the jaws opened and the finger 57 withdrawn so that the finished article can be ejected.

Title: Process for the extraction of wool-grease or other fatty material and soap from wool-scourers' liquors or similar trade wastes and the purification of the liquors for re-use
Inventor: JONES GWYNFRED
IPC: C11B11/00
Filed: 1946-01-16
Abstract: Wool-grease or other fatty matter and soap or synthetic detergents having a like effect, are recovered from wool-scourers' liquors or similar trade wastes, by agitating the liquors in the presence of a solvent composed at least partly of a polar compound or compounds and which is at least partially immiscible with water and is capable of dissolving the grease or fatty matter and soap or synthetic detergent having a like effect.  The solvents specified comprise fusel oil, amyl alcohols, normal- or iso-butyl <PICT:0617250/III/1> alcohol, or cyclohexanol.  The soap &c. may then be recovered from the extract solution by washing with water, with or without addition of another substance such as a petroleum fraction to decrease the solubility of the soap &c.  The soap &c. and the fatty matter are finally obtained from the aqueous solution and the remaining extract solution by removal of solvent respectively. The liquor separated from the first extract solution is regenerated scourers' liquor and may be re-used. In a suitable plant applied to wool scourers' liquors, the liquor is passed through a screen 2 and a sand-settling tank 3, to a mixing tank 8 for optional treatment with a small proportion of fusel oil or butanol to break the emulsions prior to the main solvent extraction preferably by counter-current in a column 12.  The fusel oil or butanol in the latter are preferably used in the proportion of at least two parts by volume to one of the aqueous liquid, the column being preferably at 55 DEG  C.  The raffinate flows to a continuous still 15 for solvent stripping to recover regenerated scourers' liquor which may be further purified if desired.  The extract solution flows to a second extraction column 21 for washing with warm water, the latter preferably containing small proportions of NaOH and an alkaline buffering agent such as trisodium phosphate.  The raffinate flows to a still 27 for solvent stripping to recover the soap &c. solution, and the remaining extract solution flows to a continuous still 31 for solvent stripping to recover the crude wool-grease.  In a modification of the working of the process, the optional breaking treatment is carried out in the mixing tank 8, with or without an agglutinating re-agent such as bentonite, and the clear regenerated scourers' liquor separated from the sludge and scum, which latter alone passes to the main solvent extraction stage.

Title: Process for the preparation of polyfunctional diazonium halides
IPC: G03F7/021
Filed: 1962-01-18
Abstract: Diazonium halides containing more than one diazonium group are prepared by a process which comprises condensing a substituted or unsubstituted diphenylamine-4-diazonium salt with formaldehyde in hydrofluoric, hydrochloric or hydrobromic acid and recovering the diazonium halide as a product free from metal salts by evaporating the reaction solution to dryness at a temperature not exceeding 70 DEG  C. (if necessary with previous removal of sulphate ions) or by precipitating it by means of an organic non-solvent.  The substituents in the diphenylamine nucleus may be alkoxy, alkyl or carboxyl groups or halogen atoms.  Sulphate ions may be removed as a salt (e.g. an alkaline earth salt) of low solubility. In the recovery by precipitation the reaction solution may first be diluted with an organic solvent e.g. methanol, ethanol, dimethylformamide and dimethyl sulphoxide in which the diazonium halide is soluble and the halide is precipitated by the addition of an organic non-solvent such as straight or branched chain aliphatic alcohols of 3-5 carbon atoms and aliphatic ketones such as acetone and methyl ethyl ketone.  The products are either the acid diazonium halide hydrohalides or mixtures thereof with the neutral diazonium halides.ALSO:Diazonium halides containing more than one diazonium group are prepared by a process which comprises condensing a substituted or unsubstituted diphenylamine-4-diazonium salt with formaldehyde in hydrofluoric acid, hydrochloric acid or hydrobromic acid and recovering the diazonium halide as a product free from metal salts by evaporating the reaction solution to dryness at a temperature not exceeding 70 DEG  C.
